hi guys today i will explain to you how to use erdafitnib for height safely
ts took kinda long time so id preciate some feedback so lets get into it
yh i asked ai to format and correct typo mistakes im sowy
KEY POINTS
HOW DOES IT WORK?
RESULTS FROM STUDIES + DOSAGES
HOW TO RECONSTITUTE RAW ERDA POWDER
SIDE EFFECTS + SOLUTIONS
POTENTIALLY SYNERGESTIC COMPOUNDS
TLDR
Simplified: You can think of FGFR3 as the brake on growth in long bones. People who have a lot of it / high FGFR3 almost always have dwarfism / achondroplasia (which basically means you're extremely short).
Study on FGFR3 and height: pubmed.ncbi.nlm.nih.gov/8078586
Started at age 14, he used 5mg and then reduced to 3mg because of bone and stomach pain. He used it for a total of 6 months (his phosphate levels were fine at that dosage, btw). The study also said "dramatic growth spurt" — I couldn't find any cm values though.
Rapid Height Growth::https://www.sciencedirect.com/science/article/pii/S2405844024069184#sec3
Started at age 15.3, he used 7mg and then reduced to 5mg after 5 months due to high phosphorus levels, and added a phosphate binder. He grew 14.3cm in 9 months — approx 1.6cm per month — but sadly he grew too much too fast and got severe scoliosis issues.

Started at age 13, he used 5mg and was later reduced to 4mg due to lower leg pain, diarrhea, and nail changes. He grew 9.8cm in 6 months — approx 1.6cm per month.
So what dosages should we use?The studies showed us that a dosage of 4-6mg or more is very likely to give us around 1.5cm of height growth per month, and this dosage is fairly tolerable with minor sides. You could go for more, up to 8mg per day, but atp the sides are very bad — go for it if you can handle it.
btw heres a foto of me doing it
A good way to do it: Geometric Dilution (mixing erda with a powder to dilute)
Things you need:
So we will be making a concentration of 2 mg erdafitinib per 1 gram of taurine, and we're going to make 100 capsules/servings. You can even use ChatGPT for the math on this.
(!THESE SIDE EFFECTS OCCURED IN PATIENTS RUNNING IT AT 8-9MG!! so you probably will have less sides if your dosage is less, and also you will be doing 5-week cycles so these will not likely reach severe levels
Btw idk who has to hear this but don't use erdafitinib if you're pregnant — it's toxic for your baby.
Resolution?
Annoying but unharmful side effects that might occur (I strongly recommend you use NAC 1500-3000 mg daily — it helps):

1.HOW DOES IT WORK?
Erdafitinib is a pan-FGFR tyrosine kinase inhibitor. It inhibits FGFR1–4. The suppression of FGFR3 is the primary mechanism that promotes height growth by chondrocyte proliferation that drives endochondral ossification, resulting in increased linear growth. And also widens the growth plates.Simplified: You can think of FGFR3 as the brake on growth in long bones.

3.HOW TO RECONSTITUTE RAW ERDAFITINIB POWDER
First off, I want to say that YOU SHOULDN'T simply measure raw erda and put it in a capsule and eat it, because it's super hard to accurately measure mgs like 5 or 4.btw heres a foto of me doing it
A good way to do it: Geometric Dilution (mixing erda with a powder to dilute)
Things you need:
- Erda powder
- Dilution powder — I recommend taurine since it's very cheap, around 10 euros for 1 kg, which is more than enough. You can use any edible powder like glycine, creatine, etc.
- 0.001g scale to measure your erdafitinib
- Food scale to measure your dilution powder (let's say we're using taurine)
- Capsules — GET SIZE 000 ONES!! I found out they can contain a maximum of exactly 1 gram of powder, which is good because you don't have to measure every single capsule to 1g and instead just fill the capsules as much as possible.
- Silica gel packet for longer shelf life
- Air-tight container — I like the amber containers from Amazon, just search "air tight amber jar" on Amazon.
So we will be making a concentration of 2 mg erdafitinib per 1 gram of taurine, and we're going to make 100 capsules/servings. You can even use ChatGPT for the math on this.
- Get your 0.001g and carefully measure out 200 mg of erdafitinib and add it to a bowl to mix.
- Get your food scale and measure out 100 grams of taurine (your dilution) and add it to a separate bowl.
- (You can eyeball this part.) Add the same amount of taurine as you have erda (so 200 mg of taurine right now) and add it to your erda bowl and mix + crush that stuff good.
- Do it again — add the same amount of taurine, so 400 mg now, to your erda container and mix it good.
- Now again, so now add 800 mg of taurine to your bowl and mix + crush it.
- Keep going until you have added all 100 g of taurine to your bowl of 200 mg erda. What you have now is 100 grams of taurine, and each gram of taurine contains 2 mg of erda.
- Add 1 gram of your mixture to a capsule. Now you've got your erda capsules, each containing 2mg erdafitinib.
- Store the erda powder in a cold, air-tight environment with a silica gel packet so it can absorb the air and make it last longer.
4.SIDE EFFECTS + SOLUTIONS
Main side effects you should worry about(!THESE SIDE EFFECTS OCCURED IN PATIENTS RUNNING IT AT 8-9MG!! so you probably will have less sides if your dosage is less, and also you will be doing 5-week cycles so these will not likely reach severe levels
Btw idk who has to hear this but don't use erdafitinib if you're pregnant — it's toxic for your baby.
1. Hyperphosphatemia / High Phosphate Levels — affected 76% of patients
HERE'S A DETAILED GUIDE A FRIEND MADE ABOUT PHOSPATE LEVELS, IT'S WORTH CHECKING OUT: https://looksmax.org/threads/erdafitinhib-full-phosphate-guide-mitigate-the-sides.2299244/Resolution?
- Keep your phosphate levels under 7 mg/dL
- Keep your dietary phosphate intake to 600-800 mg
- Use an oral phosphate binder like Sevelamer 800-1600 mg with every meal, 3x a day
2. Eye-Related Problems (you won't go fucking blind my nigga)
- Dry eyes — affected 29% of patients. Use eye drops and you're good.
- CSR / Central Serous Retinopathy / Blurred Vision — affected 28% of patients, and only 4% reached severe levels. Deal with it because it's only temporary. Dorzolamide eye drops can help reduce the fluid build-up under the retina, which is what causes blurry vision.
3. Scoliosis — this is fairly simple to avoid
Depending on how much you actually grow, you should cycle it on and off. If you're growing more than 1.2cm per month, then cycle erdafitinib 5 weeks on and 2 weeks off so your tissue can adapt and your bones don't grow too fast and outgrow your tissue. you can cycle it regardless if youre growing less then 1,2cm to stay extra safe.Optionally Vitamin D3 + K2 for bone mineral health, and collagen supplements for tissue help (don't get the powder — it's the worst fucking stuff I ever tasted and I learned it the hard way and wasted 30 euros).Annoying but unharmful side effects that might occur (I strongly recommend you use NAC 1500-3000 mg daily — it helps):
- Mouth dryness + slight inflammation (almost guaranteed): Drink some water and maybe some tea in the morning.
- Diarrhea (very likely; I personally got this side effect on day 2 of erda): Use Loperamide 2 mg after each bowel session.
- Nail disorders (62%): Deal with it, your nails grow back.
- Dry skin/face (37%): Oil/moisturize yourself.
- Slight hair loss (26%): Unlikely, and you can use some minoxidil.
- Fatigue (54%): People say they "feel like a cancer patient" — you will be very tired. Get some caffeine in the morning.
- Weight loss: You get very full, not very hungry — basically some free reta.
- Nose bleeds: Often every day. Deal with it or do something sinister with it.

5. Potentially synergistic compounds to add for height (do your own research on these)
- HGH — 0.07-0.1 mg per kg per day
- Halotestin
- Anavar
- Vosorotide
- Etc...
6. TLDR
Use 4-6mg erda daily, use eye drops for dry eyes, use loperamide 2mg after each diarrhea session, cycle erda 5 weeks on 2 weeks off to avoid scoliosis issues, add some NAC supplement 1.5-3g.Attachments
